Abstract
Sample media for the analysis of analytes in a fluid test sample includes a carrier, at least one test field on the surface of the carrier including at least one reagent reactive with the analytes and capable of providing a detectable response. A non-visible bar code formed by at least two distinct non-visible marker fields is located on the carrier. The marker fields are configured to reflect electro-magnetic (EM) radiation within one or more ranges of non-visible wavelengths to form a coded sequence of reflectances correlated to identification of the sample media.
